Lid Closers

Written by Sierra Rein

Lid closers are usually the second to last step in the filling and packaging assembly line. Second only to the labeling machines, lid closing machines provide a continuous motion of production between the lid cappers and the labelers. The specific choice of machine, however, depends on a number of factors dictated by the type of containers to be used and the method by which the machine will operate.

The simplest lid closers are manual crimpers that use leverage to crimp the edges of a lid around the outside "lip" of the bottle or pail. Some hand-held pneumatic machines are able to twist lids and caps onto bottles and round containers with enough torque to make the process effective, even when operated by a single person. However, the product outflow will depend on the speed and reliability of the particular lid closer the company decides upon.

Automatic pail lid closers utilize rolling mechanisms to quickly place pressure along the top edge of a lid, snapping it into place on the lip of the pail. The pail sits on a conveyor belt while the lid is placed on top either by a machine or by a human operator. The conveyor belt moves the pail and lid combination underneath the rollers, which are adjusted to the right height to apply the right amount of pressure for closure.

For Many Applications, Choose Versatile Lid Closers

If a company offers its customers a wide variety of product container sizes, from very small pocket bottles to large bulk pails, it is essential for that company to purchase lid closers that can process a number of different container, lid and cap sizes. It should purchase the right number of machines to handle the particular outflow target rates, and supplement with smaller or hand-held machines as necessary to take up the slack. After all, the more streamlined and more efficient the process is, the more business and outward growth the business will experience.
